Let's divide 42554481 by 407
We're looking to find how many times 407 goes into 42554481.

On to step 1:
407 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 407

Let's proceed to step 2:
The number 407 fits into 42 0 times, leaving a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Append the next digit (5) from the dividend to 42 and continue with: 425 / 407

Going ahead to step 3:
425 divided by 407 is 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 407 from 425 and we're left with 18.
Append the next digit (5) from the dividend to 18 and continue with: 185 / 407

Moving on to step 4:
The number 407 fits into 185 0 times, leaving a remainder of 185.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 185, we get 185.
Bring next digit (4) of the dividend behind the 185 and repeat the process: 1854 / 407

Moving on to step 5:
When dividing 1854 by 407, we get 4 with a remainder of 226.
Put 4 as the next digit of the answer. 
Result so far: 104.0
Subtract 1628 from 1854 to get 226.
Include the next digit (4) from the dividend after 226, then repeat: 2264 / 407

Moving on to step 6:
407 goes into 2264 5 times with a remainder of 229.
Write down 5 as next digit of the result. 
Result so far: 1045.0
If we subtract 2035 from 2264, we get 229.
Fetch the next digit (8) from the dividend, attach it to 229 and continue: 2298 / 407

On to step 7:
If we divide 2298 by 407, we get 5 and a remainder of 263.
Use 5 as the next digit of our solution. 
Result so far: 10455.0
Subtracting 2035 from 2298 leaves us with 263.
Bring next digit (1) of the dividend behind the 263 and repeat the process: 2631 / 407

Moving on to step 8:
2631 divided by 407 is 6 with a remainder of 189.
Record the quotient 6 as the next digit in the result. 
Result so far: 104556.0
If we take 2442 away from 2631, we end up with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Moving on to step 9:
407 can be fit into 1890 4 times, resulting in a remainder of 262.
Use 4 as the next digit of our solution. 
Result so far: 104556.4
Subtract 1628 from 1890 to get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Step 10:
2620 divided by 407 is 6 with a remainder of 178.
Put 6 as the next digit of the answer. 
Result so far: 104556.46
The remainder is 178 after subtracting 2442 from 2620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Moving on to step 11:
The number 407 fits into 1780 4 times, leaving a remainder of 152.
Record the quotient 4 as the next digit in the result. 
Result so far: 104556.464
Subtracting 1628 from 1780 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 12:
407 goes into 1520 3 times with a remainder of 299.
Write down 3 as next digit of the result. 
Result so far: 104556.4643
Subtract 1221 from 1520 to get 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Going ahead to step 13:
407 goes into 2990 7 times with a remainder of 141.
Write down 7 as next digit of the result. 
Result so far: 104556.46437
Deduct 2849 from 2990 and we're left with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Going ahead to step 14:
407 can be fit into 1410 3 times, resulting in a remainder of 189.
Write down 3 as next digit of the result. 
Result so far: 104556.464373
If we subtract 1221 from 1410, we get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Moving on to step 15:
1890 divided by 407 is 4 with a remainder of 262.
Use 4 as the next digit of our solution. 
Result so far: 104556.4643734
The remainder is 262 after subtracting 1628 from 1890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Step 16:
When dividing 2620 by 407, we get 6 with a remainder of 178.
The next digit of our result is 6. 
Result so far: 104556.46437346
If we subtract 2442 from 2620, we get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

The final outcome is 104556.46437346, with a leftover of 1.78e-07.
